Great product.By Billon 8/30/2010

Have yet to get a reading other then zero from a phosphate test since i started using this product. Very low dust, once flow is set through reactor dont have to mess with and it never clumps.

Once you start to use it, you know you’ll continue to use it so get the biggest container you can…it’s the best value I found!

Tumbles very nicely, takes Phosphates out of the water. I was using Two Little Fishes Phosban but this out performs it and is cheaper.

Works great in my BRS dual reactor, phosphate levels are now great.

Few things in Reefing I live by and GFO is one! It cuts my phosphates to 0 using my Hannah Phosphate reader! This is a great buy if your using a reactor because not only are you getting a great price but the Reef Calculator on the homepage tells you exactly how much to use. I do wish however it came with a measuring tool.

This stuff is great! When I first started this my phosphate levels were above 1.0. After a few weeks I was way down in the point .1s. Now I do it regularly and only have to replace the media every 5 weeks in the dual reactor.

I just wanted to share that one thing i love about this product is is alot drier than the phosloc brand so it tumbles alot better in my reactor and does not require as much force from the pump. Also works great at removing phosphates i know when to change it because algae starts growing on my glass again. :)

I recomend this GFO to anyone with phosphate problems. I have made GFO a part of my regular maintainance and I think my corals love me for it.

Great product and no difference between this and higher priced products. It does create some dust but all GFP products do. I do not even bother checking my phosphates. All I know is I do not have unwanted algae growth.
